Frequently Asked Questions

What is the OSG Spiral Point Tap 2858008 used for?

The OSG Spiral Point Tap 2858008 is a general-purpose tap designed for through-hole threading in metals. Its spiral-point geometry pushes chips forward, reducing clogging. It is commonly used in automotive, aerospace, and general manufacturing for creating UNF threads in steel, aluminum, and alloys.

What are the specifications of the OSG Spiral Point Tap 2858008?

This OSG tap has a thread size of 5/8"-18 UNF, with a tolerance class of H7 / 2B-3B. It features 3 flutes and a plug chamfer. The manufacturer part number is 2858008. It is designed for through-hole applications and is made from high-speed steel for durability.

Where to buy the OSG Spiral Point Tap 2858008 worldwide?

You can source the OSG Spiral Point Tap 2858008 through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead times; we supply this tap to procurement teams globally.

How to select the correct OSG Spiral Point Tap for UNF threads?

To select the correct OSG spiral point tap, match the thread size (e.g., 5/8"-18 UNF) and tolerance class (H7 / 2B-3B) to your application. For through holes, a plug chamfer and spiral point design are ideal. Ensure the tap material suits your workpiece—OSG taps are typically high-speed steel for general use.
